Memnarch is a mono-blue control commander whose two abilities combine into a brutal theft engine: turn anything into an artifact for , then steal it for . You ramp hard with artifact mana, protect Memnarch, then untap and use big mana to permanently strip every threat off your opponents' boards before closing with overwhelming card and resource advantage.
Permanently steals lands, creatures, planeswalkers — anything — once they're artifacts, which is unmatched board control.
Mono-blue gives access to the format's best counterspells, card draw, and untap/clone effects.
Synergizes with artifact ramp, cost reducers, and untappers that turn his pricey abilities into a repeatable loop.
Theft is permanent and color-agnostic, so he steals from any deck regardless of opponents' colors.
A 7-mana, slow, mana-hungry commander that does nothing the turn it lands without protection.
Abilities are expensive to activate repeatedly without untap or cost-reduction support.
Huge threat magnet that invites removal, counterspells, and the whole table ganging up.
Mono-blue lacks efficient creature removal and struggles to interact at instant speed with resolved threats absent the steal engine.
Vulnerable to artifact wipes and Stony Silence / Karn effects that shut off your mana base.
Legendary Artifact Creature — Wizard
, doubling your theft per activation.
